Pyrimidine, also known as 1,3-diazobenzene, is a heterocyclic compound with the chemical formula C4H4N2. Pyrimidine is formed by substituting 2 nitrogen atoms for 2 carbons in the meta-position of benzene. It is a diazine and retains its aromaticity. Derivatives of pyrimidine widely exist in organic macromolecular nucleic acids, and many drugs also contain pyrimidine rings. In nucleic acids, three nucleobases are pyrimidine derivatives: cytosine, thymine and uracil. There are a variety of pyrimidine-containing drugs on the market, most of which are kinase inhibitors.
BioAge Labs presents preclinical data for apelin receptor agonist azelaprag for obesity demonstrating significant improvements in weight loss and body composition when combined with incretin drugs.
Azelaprag is an orally available small molecule agonist of the apelin receptor APJ. Apelin is an exercise-induced signaling molecule (exerkine) that acts on APJ to mediate many of the metabolic benefits of physical activity.
